To @ZZ luft-07m i6 may concern:

Be it known that we, Louis PrrNes'r and SUMNER A. Bnnis, citizens of the United States, residing, respectively, in the city, county, and State of New York, and at Springeld, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Cable-G1ip Beams and Supporting Devices Therefor, of which the following is a specification.

This invention relates to improvements in supports on the truck-frames of cable-impeded cars for the grip-beams which carry the cable gripping or engaging devices, the purpose thereof being to present and maintain such gripping devices at all times and under all motions of the car and its truck to their proper relations to the cable, the specific objects to be obtained in the present supports being` their capability, first, for permitting endwise movement of the grip-beam therein in relation to the length of the truck; secondly, for permitting a lateral movement of said grip-beam bodily, or as to its either end, insaid supports, and, thirdly, for permitting an oscillation or rolling movement of the said grip-beam by its upper or bearing end portions in said supports; and to these ends the invention consists in the construction and combination of parts, substantially as will hereinafter more fully appear.

In the accompanying drawings, Figure 1 represents a grip-beam and its supports, the latter being attached to the transverse braces or girders of a car-truck, showing one of said transverse girders as in horizontal section with some parts of the grip beam support thereat in horizontal section, other parts thereof being removed. Fig. 2 is a vertical crosssection of said truck cross brace or girders, and in part a side elevation and in part alongitudinal section ou line fr x of the grip-beam and its supports. Fig. 3 is aperspective view of one of the grip-beam end supports, with one of the arc-shaped confining bars or loops swung into an open position. Fig. 3n is a View of one of the arc-bar securing-pins detached. Fig. 4 is a perspective View of the grip-beam, some portions thereof being broken away. Fig. 5 is a rear view of one of the grip-beam supports as removed from the cross-- Serial No. 270,341. (No model.)

length alittle shorter than the distance between 6o the inner faces, a, of the grip-carriages, so that it may have a slight endwise play between said inner faces of said carriages. Thegrip-beam at each end, as shown in Figs. l, 2,

and 4, is provided with an enlarged cylindrieal- 63 shaped head, I), and has a socket, f, therein,

4 in which may be placed a spring, d, the said spring projecting beyond the ends of said beam-heads and occupying, when the beam is supported in place in the grip-carriages, the 7o spaces between the ends ofthe beam-heads and the inner faces of the said carriages. The said springs are to be preferably formed of blocks of rubber, although stiff spiral or other form of spring or elastic cushion may be employed in lieu of the rubber springs.

The grip-carriages B B are preferably movable along the length of said cross-transomsthat is, laterally of the car-truck-and said grip-carriages are provided with sockets or 8o restsg for the ends of the grip-beam, which permit, in addition to the endwise motion of said grip-beam before mentioned, a partial rotation or roll of the said beam by its bearing ends therein, and said sockets are formed separable,or so as to be divided as to their upper and lower bearing portions or walls, whereby the bearing ends of said grip-frame may be either lifted out thereof or dropped therefrom, and, as particularly shown in the drawings, Sheets l and 2 thereof, each gripcarriage B consists of a back plate or outer wall, h, provided at each end with forward extension, j, terminating in short inwardly-extending lugs k, and arc-shaped bars or rigid loops Z, having eye-heads m at each end, are confined in place in said carriage by the pins a passing through the inner lugs, It', and the back plate of the -carriage and through the intermediately-disposed loop-eye heads m wit-h their concave which keys or split pins t may be passed, and

also through cross-holes s in the pins n, where;

. by said pins will be held against escape from their positions for confining the loop-bar ends. Said pins at their outer ends may be provided with ring-eyes u, for the connection therewith of chains o, which by their other ends are fastened to the carriage.

To the rear of the grip-carriage is hung a pair of rollers, 10, which have a bearing in a horizontal line on the cross-transoms, or some part thereof, which bearing parts, for convenience of construction, are here shown as consisting of plates 12, secured to the inside of said transoms, having portions of their faces towardl said transoms recessed, as at 14, a headed stud, 15, secured to each of said carriage' back plates and passing through a horizontally-elongated slot, 16, in its respectivelyadjacent fixed transom-plate 12, serving as a limit to the lateralmoveinent of said carriage on the truck. I

Each carriage back plate, h,as shown in Figs.

1, 2, and 3, is provided with an outwardly-eX- tending horizontal flange, 17, underlying the transomplate 12, which serves to insure with greater certainty an even and steady lateral movement of the carriage.

The grip-beam C, as shown, is at its upper side provided with handles 20 20, for convenience in lifting same from the carriage sockets.

In Figs. 6 and 7, in lieu of forming the separable grip beani receiving sockets g with pivotal arc or loop bars, arest-block, 22, is supported by bolts 23, loosely passing through the inward carriage-extensionsj and said restblock 22, said rest-block being on its upper side of a concave shape to permit the roll therein of the grip-beam end, and above said grip-beam end one or more bolts,25,are loosely passed through said carriage-extensionsj, from which construction the same results are attained in substantially the same ways, but under modified formations of some ot' the parts the endwise and rolling motion of the grip-beam on the laterally-movable carriage being permitted, as plain.

What we claim as our invention is- 1. The combination, with a car-truck, of' a grip-carriage supported and laterally movable thereon, provided with a rolling bearing for a grip-beam, substantially as described.

2. rlhe combination, with a car-truck, of a gripcarriage laterally movable thereon, provided with a rolling bearing for a grip-beam, the walls of which bearing areseparable, sub- 5 stantially as described.

3. The combination, with a car-truck and a pair of grip-carriages supported and laterally movable thereon, provided with rolling bearings for the grip-beam, of a grip-beam sup` ported in said bearings and having a length f.less than the distance between the opposing outer Walls of said grip-carriages, whereby it may have an endwise movement, substantially as described.

4. The combination, with a car-truck and a pair of grip-carriages supported and laterally movable thereon, provided with rolling bearings for the grip-beam, of a grip-beam supported in said bearings and of a length less than the distance between the opposing outer walls of said grip-carriages, and springs between the ends of said grip-beam and said walls of the carriages, substantialiy as described. v
